The Bluetooth Special Interest Group (SIG) has launched a new debate in the field of wireless technology with the release of the new version of Bluetooth, Bluetooth 6.0, in 2024. This new standard mainly aims to make connectivity between wireless headphones and smartphones more secure, faster, and more efficient.
Current Bluetooth devices often experience a 50 to 100 millisecond lag between sound and visuals when watching videos or playing games. Bluetooth 6.0's ISOAL (Isochronous Adaptation Layer) technology divides audio data into smaller chunks and processes them faster. This can reduce real-time latency to 20 milliseconds. This will reduce the need for wired headphones, especially for mobile gamers.
The most talked-about feature of this version is Channel Sounding. It provides precision of up to 10 centimeters to find lost devices. Previously, such accuracy required an expensive ultra-wideband (UWB) chip. But now, even cheap and ordinary headphones can be easily found with Bluetooth 6.0.
In addition, the new technology also helps reduce battery consumption. Now devices do not have to constantly search for a 'signal' to connect. Instead, they will recognize previously connected devices as soon as they come within a certain range. This will make the process of multipoint switching (using one headphone on two devices in turn) easier and hassle-free.
Despite many improvements in Bluetooth 6.0, it still cannot provide completely wireless lossless audio. In the future, there are plans to make high-quality audio streaming possible by increasing speeds up to 7.5 Mbps.
Currently, only a limited number of devices support Bluetooth 6.0. These include new smartphones such as the Google Pixel 10, iPhone 17, and Xiaomi 16. On the headphone side, the Earphones Air Pro 7 Plus and Edifier Duo S2 have already adopted this technology. While smartphone manufacturers have adopted it quickly, it is estimated that it may take until 2026 for headphone companies to fully implement it.
